When want to remember things, we often stick them in our smartphones or write them on paper, but sometimes we're at the mercy of our brains. When you have to keep something in mind but have a bad habit of forgetting, just imagine something crazy in conjunction with it.

Redditor TheSonofBillMurray has a terrible memory and requested others to help improve it with some clever trick. Among the many suggestions was doing something out of the ordinary. Many people suggested this in various ways, but here's one particularly good explanation from redditor zeehero:

The best way I remember something is if I actually do something a little out of the ordinary. By myself, I'm pretty quiet, so when I have something like remembering if I locked my door before leaving my place, I'll say "I've locked this door, Scotty." That way if I have to remember, I can just think to myself "I told Scotty I locked the door. He shouldn't be complaining."

It sounds crazy, but it works. Do something strange, and note doing that strange thing. That way you can remember mundane things. You provide a mental hook to hang something on.

That pretty much sums up the trick. Your brain prioritizes the unusual, so when you turn something normal into something abnormal, your brain takes notice and makes its memory a priority.
